Problems solved by technology

However, the test piece on the test piece table is impervious to water, so the bottom is set to be porous, which cannot make the water formed by melting snow on the surface of the test piece reach the inclined deflector below smoothly, and the water dissolved on the surface still has to flow from the side of the test piece. Flow down, which will affect the accuracy of the test, and will increase the flow path of the dissolved water, thereby increasing the test time

Abstract

The invention provides a snowfall and snow-melting simulating device. The device comprises an environmental cabinet, a control console and a compressor, wherein the environmental cabinet comprises an ice crusher, a test piece platform and a collecting and weighing device; the ice crusher is fixedly arranged at the top part of the environmental cabinet, the collecting and weighing device is arranged at the bottom of the environmental cabinet, the test piece platform is fixedly arranged above the collecting and weighing device, the bottom of the ice crusher is designed to be a replaceable screen bottom, and the test piece platform has a certain inclining angle to ensure that molten snow water can flow down smoothly. The snowfall and snow-melting simulating device can simulate the snowfall and snow-melting processes and is low in manufacturing cost, the required equipment is simple and easy to operate, the device is used for evaluating the snow melting effects of snow-melting road surfaces by comparing the snow-melting rates of the different road surfaces under the same condition, for an instance, the device is used for comparing and analyzing the snow-melting rates of a common road surface and a road surface with various additives, and thus the varieties or the content of the additives can be determined to facilitate smooth scientific research.

Description

technical field [0001] The invention relates to a snowfall and snowmelt simulation device. Background technique [0002] In places with perennial snowfall or heavy snowfall, it is easy to cause traffic accidents such as car accidents due to icy roads after snowfall. Therefore, road builders or relevant departments should choose road components with good snow melting effect before construction, so that Build roads with excellent snow melting effect, effectively reduce the occurrence of traffic accidents. [0003] With the improvement of traffic safety awareness, people are aware of the adverse impact of road icing on traffic accidents, and more and more researchers have begun to study snow-melting roads. In order to facilitate indoor experiments, snow simulation devices have not been There is no reasonable, mature, and rapid evaluation of the indoor test snow melting rate of additive self-melting pavement, steel fiber heating and other snow melting pavement. [0004] The ut...
